roNGUED'sAsl-L SPECIFICATION forming part of Letters Patent No. 732,298', dated Julie 30, 1903i: Application tiled February 26,1900. Serial No. 6,633. (o modela)l 'it from a iiXed relation with such member.

lWIy invention is adapted for use in a pivoted. window described and claimed in my e United States Patent No. 618,462, issued January 3l, 1899, in which a grooved slide-bar is pivoted to a grooved stile so that the grooves register with each other, and a tongue is movably arranged to tit in and be moved out of the grooves to fix and uni-lx the stile and sliding bar with relation to eachother.

The object of my present invention is to prode simpler means for holding the sash in and Veleasing it from a fixed relation with the slidepar which is pivoted thereto. I do this by provifi ".g the stile with a groove in its edge, which will fully seat the tongue, and providing certain simple and positive means for moving the tongue to project it into and withdraw it from the groove in the slide-bar. I carry out my invention by pivoting the tongue to a lever which is pivoted tothe stile and is of such length between its fulcrum and its pivotal connection with the tonguethat when the ever is thrown in one direction it will throw the edge of the tongue beyond the edge of the stile, thereby to insert a portion of the tongue into the groove of the slide-bar, which is pivoted to the stile, while another portion of the tongue remains in the stile.

Another object of my invention is to provide the most simple and inexpensive means for accomplishing the object above stated.

The accompanying drawings illustrate my handles of the levers in the unlocking posilever pivoted to the tongue and to the stile.

Solid lines show the parts in the unlocking position. Dotted lines indicate the locked position. Fig. 4 is a fragmental view looking at the stile a from the right. Fig.y 5 is a detail horizontal section through the stile, slide-bar, and tongue, showing their relative positions.

A indicates the sash and a a the grooved stiles of the sash.

In Figs. 2 and 3, l indicates a groove eX- tending along one edge of the stile.

2 indicates a slot extending from the groove through the stile. l) indicates a lever in the slot and groove and provided at one end with a rounded catch 3.

c indicatesa tongue to play in the groove l and provided with a rounded seat 4, in which the rounded catch 3 is held, thus forming a pivotal connection between the lever b and the tongue c.

cl indicates a pivot which pivots the lever to the stile. The pivot d is Xed to the stile and iits a circular pivot-hole in the lever, so that the lever has no play except to vibrate on said pivot.

Y e indicates a bar pivoted to the stile and provided with a groove 5, into which the tongue wide as to allow the rounded catch 3 to be.

Withdrawn therethrough, but is of sufficient width to allow the required play of the lever for the purpose of operating the tongue to throw it into and out of the groove of the slidebar. Desirably the tongue and the head 3 of IOO the lever are of the saine thickness, so that the head is contained within the notch 4, being flush with the sides of the tongue. The slot 2, through which the lever is inserted, may be the same width across as the groove 1, in which the tongue c works To assemble the parts, the lever b will be inserted through the slot 2 and the groove 1, thus bringing the rounded catch 3 beyond the edge of the stile. The tongue will then be brought into position with the catch 3 seated in the seat 4, as shown in Fig. 2. Then the tongue carrying arm of the lever will be drawn into an oblique position relative to the tongue and stile, as shown in Fig. 3, and the stile and lever will then be bored with a hole through which the pivot d will be inserted to pivot the lever to the stile, care being taken that the length of 'the arm between the pivot d and the pivotal connection formed between the tongue and lever at 3 4 will be sufficiently great to cause'the tongue to protrude from the groove 1 when the arm 8 is thrown toward a right angle with the stile, as indicated in dotted lines in Fig. 3.

In practical operation when it is desired to unlock the window, so that it can be turned on the pivot f g, the lever b will be thrown into position to bring its arin 8 oblique to the groove 1, as indicated in solid lines in Fig. To lock the window against turning on its pivot, the lever will be thrown to bring the arm S at right angles to such groove.

By preference the arms 8 9 of the lever b are at a slightly obtuse angle to each other and the pivot-point at the bend is located as near the inner edge of the stile as possible, so that when the lever is in locking position the arm 9 will be brought nearly or quite parallel with the stile. This will give sufficient leverage to the handle to easily operate the tongue and yet will prevent it from standing out from the stile so far as to be in the way.

The groove l is just wide enough to seat the tongue, so that when the lever is pivoted in place, as shown, the walls of the groove 1 serve at all tilnes to hold the catch 3 from being withdrawn laterally from the notch-seat 4.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. In a sash, a grooved stile and a grooved slide-bar pivotally secured thereto with the grooves registering with each other, the stile being provided with a slot extending from the groove inward, a tongue in said grooves, and an obtuse-angled lever pivotally mounted at its bend in the slot near the inner edge of the stile, one end of which is pivotally connected with the tongue and the other end is provided with a handle and is adapted to stand nearly parallel with the stile when the parts are in their locked position.

2. In a sash, a grooved stile and a grooved slide-bar pivotally secured thereto with the grooves registering with each other, the stile being provided with a slot extending from the groove inward, a tongue in the grooves, one edge of which, opposite the slot in the stile, is provided with an open-mouthed rounded pivot-seat, and a substantially L-shaped lever pivoted in the slot near the inner edge of the stile, one end of which is provided with a rounded head to t in the seat of the tongue and the other end is provided with a handle and is adapted to stand substantially parallel with the stile when the parts 4are in their locked position.

3. In a window-sash, the combination of a tongue having near one edge a rounded seat consisting of a circular notch havingamouth narrower than the diameter thereof, said inouth opening at the edge of the tongue, and a pivoted bent lever having a circular head fitting in and containedinside said notch, said head being of a greater diameter than the narrowest portion of the mouth of the notch.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, California, this 19th day of February, 1900.
